Variable Range Simulator (VRS)

Download Brochure

The VRS - Variable Range Simulator – is a system used for range simulation and testing the accuracy and functionality of Laser Designators and Laser Range Finders (LRF).

The VRS is used for functional testing of LRFs operating in a broad range of wavelengths from 850nm to 1570nm, with the option of configuring up to three discrete wavelengths to be incorporated into the VRS.
